4341 was a leftover from an earlier version of the routine. Move
4342 several routines out to avoid deep nesting and indentation.
4343 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
4344 parameter Do_Checks to Post_Errors. Update the comment on usage.

4518 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
4519 just direct dependents. If this is actually an abort, each task
4520 will take care of aborting its dependents, so all dependents will
4521 get aborted, as before. However, when this is called the second
4522 time from Vulnerable_Complete_Master "for convenience" (i.e. to
4523 kill off tasks waiting at terminate alternatives), aborting
4524 indirect dependents is wrong, because it causes some unrelated
4525 tasks to get aborted.

6271 the original one. the modification of the name must preserve
6272 the source location of the original, to prevent spurious errors
6273 when compiling with style checks if the declaration involves
6274 more than one entity.
